For those scoring at home, that’s the number of times San Diego Mayor Bob Filner mentioned each team during his inaugural speech Monday.

It was an indication that Mexico’s newly-crowned championship soccer team’s following on this side of the border has grown — and that Filner may promote the border region better than any San Diego mayor in years.

Strong cross-border relations were important for former Mayor Jerry Sanders, but overshadowed by his fight against fiscal monsters. Predecessor Dick Murphy’s inaugural pledge “to reach out to our neighbors in Tijuana to solve cross-border problems” got lost (and not in translation).

Border ties were a high-profile source of pride for Mayor Susan Golding.

And it appears they also could be for Filner, who announced plans to open a Tijuana office in one of his earliest acts as mayor-elect.

Filner’s first words after being sworn in as San Diego’s 35th mayor?

“Good morning,” he said spontaneously. “Buenos dias, todos.”

Later, lifting words from prepared remarks, he added, “We’re going to tap into the vitality and potential of our neighbors to the south in part through a new border affairs office that we’re going to establish in Tijuana, and to strengthen every day our cross-border ties.”

In recent years, every newly sworn-in mayor makes a point of referring to Mexico. But Filner, 70, got it right: He pronounced it “Mehico.”

This shouldn’t come as a surprise for a mayor who called the Latino community “the margin of victory” a day before the election and then dominated the votes south of Interstate 8. Or for a former congressman from the South Bay who has sponsored many so-called “private bills,” often to seek green cards for unauthorized immigrants.

All this suggests Filner appreciates the growing power of Latinos, who now make up a third of the county’s population and 18 percent of its registered voters.

Filner’s speech revolved mostly around an appreciation for San Diego’s neighborhoods and city workers, but it also delved somewhat deeper into Mexico than other mayors have — a fact that Filner seemed to recognize.

After introducing some of the Mexican officials in attendance (many who likely made a beeline for the border after the speech so they wouldn’t miss the Xolos’ victory parade that afternoon), Filner spoke off-the-cuff about the future: “The symbol of us working together is here today, but we will continue throughout the whole administration.”

The line led into his third Xolos reference. (To be fair, Filner’s Chargers reference may have been all that fans, if not taxpayers, needed: “We’re going to make sure the Chargers stay in San Diego!”)

Ruben Barrales, CEO and president of the San Diego Regional Chamber of Commerce, raved on Twitter that Filner highlighted how the border region “should be an incubator for an innovation-based economy.”

“The relationship is bigger than any one mayor, right?” Barrales told me afterward. “But one mayor can make a big impact.”

Golding certainly did, in ways unseen since — and since then-Mayor Pete Wilson helped open the Otay Mesa Port of Entry in 1983. Golding sent about 50 city trucks to help Tijuana rebuild from flooding in 1993. After Tijuana’s police chief was shot and killed in 1993, Golding’s staff helped find a San Diego safehouse for the mayor’s pregnant wife.
